There have been many discussions about alternative sequencer firmware that differs from the MBSEQ as written by TK.  So far, only the SID 303 mode has developed into a finished product.  Of the others, the vX and the beginner's 16 step have the most active work at the moment.

Here is an attempt to summarise and collate those discussions.

The MIDIBox SID also contains a wavetable sequencer, which can be used as an [[http://www.ucapps.de/howto_sid_wavetables_3.html|arpeggiator]], or in [[http://www.ucapps.de/howto_sid_bassline.html|303 mode]] as a 3 track, 32 step sequencer.  Use of the sequencer requires either JSynthLib or the [[http://www.midibox.org/forum/index.php?topic=5680.0|303 control extension]] and the alternative v1.7303 firmware. 

The [[http://www.ucapps.de/midibox_fm.html|MIDIBox FM]] also contains the 3x32 wavetable sequencer
